SZW26-20/D101.1-B11R is a rail-mounted three-position single-pole changeover switch designed to fit standard 35mm DIN rails for easy installation. It has a rated current of 20A and is suitable for AC 50/60Hz circuits with a rated operating voltage of ≤440V (DC ≤240V) and an insulation voltage of 690V.
Key Features and Parameters:
Function: Features a "1-0-2" three-position structure, allowing switching between two loads from a single input. The middle "0" position provides complete disconnection.
Structure: Utilizes a flame-retardant casing, silver alloy contacts, and thickened copper conductors for stable conductivity, reliable insulation, and oxidation resistance.
Lifespan: Mechanical life ≥ 10⁵ cycles, electrical life ≥ 3×10⁴ cycles (operating frequency 120 times/hour).
Environmental Conditions: Operating temperature -25℃~+40℃, altitude ≤ 2000m, humidity ≤ 50% (40℃) / ≤ 90% (20℃).
Main Application Scenarios:
Suitable for applications requiring flexible installation and quick wiring, such as distribution boxes, control cabinets, and test benches, for circuit switching, load selection, equipment control, and signal measurement. The rail-mounted design facilitates system integration and maintenance, making it suitable for industrial automation, equipment power distribution, and electrical control systems.
